Answer:

The spinner is not fair

Explanation:

Given


Sections = 8


Blue = 3


Purple = 5

Solving(a): Is it fair?

The spinner is not fair because the probability of an outcome of Blue does not equal the probability of obtaining Purple.

i.e.


P(Blue) = (3)/(8)


P(Purple) = (5)/(8)


(3)/(8) \\e (5)/(8)

Solving (b):

To make it fair, the blue sections and the purple sections must be made equal (4 each)
